I read an article that said Modbus *may* not require it for runs that are 100 feet or less. Do you think that is bogus? I am going to double check around the field I work at, but I'm about 95% certain they aren't using resistors. I can promise you this: I'm going to start using them regardless of what the last guy did. That way I don't have to play that stupid game when connectivity issues arise.
